5 0
Number of moles = mass / mr of compound
mr of NH3 = 14+3(1) = 17
no of moles = 1200/17 = 70.588
                                     = 70.6 mol NH3

Can you help me answer this?

The answer is D. If you aren't consistent with your drop positions, then your data may be invalid. To be frank: it basically screws over the experiment.

A potato is shot out of cylinder at an angle of 17 degrees above the horizontal with an initial speed of 20 m/s. What is its max
madreJ [45]

Answer:

Maximum height, h = 1.74 meters

Explanation:

It is given that,

A potato is shot out of the cylinder. It is a case of projectile motion. The potato makes an angle of 17 degrees above the horizontal.

Initial speed with which the potato is shot out, u = 20 m/s

We have to find the maximum height of the potato. The maximum height of a projectile (h) is given by the following formula as :

h=\dfrac{u^2sin^2\theta}{2g}

Where

\theta = angle between the projectile and the surface

g = acceleration due to gravity

h=\dfrac{(20\ m/s)^2sin^2(17)}{2\times 9.8\ m/s^2}

h = 1.74 m

or h = 1.74 meters

Hence, this is the required solution.
